SEPARATOR MECHANISM FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 498,340, dated May 30,1893.

Application filed February 10, 1893. Serial No- 461,733. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHANNING WHITAKER, a citizen of the United States,residing at Tyngsborough, in the county of Middlesex and State ofMassachusetts, have invented acertain new and useful Improvement inSeparator Mechanisms for Ring-Spinning Frames, of which the following isa specification, reference be ing had therein to the accompanyingdrawings.

The invention is an improvement in separator-mechanisms of the class inwhich the separators are applied to suitable supports that are carriedby vertical rods, termed sepa-. rator-rods, having communicated theretoa vertical reciprocating movement resembling. that which is communicatedto the liftingrods which support the ring-rail with its rings. Theinvention relates mainly to the means for imparting to theseparator-rods and the parts which are supported thereby the verticalreciprocating movement aforesaid.

It relates also to the guides or stands by means of which theseparator-rods are held and guided in proper vertical position.

The main object of theinvention is to provide a simple, inexpensive,andconvenient arrangement and construction'of parts for communicatingmovement to the separator-rods positively in both directions, whichshall include a convenient means of eifecting the vertical shift ortranslation of the traverse of the separators that sometimes it isdesired and necessary to make without altering the extent of suchtraverse, and which shall require-or consume very little of the powerthat is used for the purpose of actuating the ring frame to which it isapplied.

Another object of the invention is to provide a stand of simple andstrong construction which shall have capacity for enabling to be madeall the adjustments ordinarily re-l I quired to be made in practice.

Another object of the invention is to pro-f vide for supporting theseparator-rail on the separator-rods in such manner as that when desiredthe separators may be turned from their working position between thespindles to a retracted or backward inoperative posi{; tion, and at anytime the separator-rail and drawings, and as is particularly pointed outand clearly defined in the claims at the close of this specification andforming a part hereof.

In the accompanying drawings, Figure 1 is a view in front elevationshowing a portion of a ring-spinning frame with the preferred embodimentof my invention applied thereto. Fig. 2 is a view in vertical section onthe line 2-2 of Fig. 1.

I In Figs. 1 and 2, 1 is the roller-beam, 2 the thread-board-diingedthereto as usual, 3 the finger-boardshinged as usual to the threadboard,athe yarn-guides secured to the finger-boards, 5 the yarns passing fromthe yarnguides 4. to the bobbins 6, through the travelers 7 on the rings8 supported by the ringrail 9, 10 the spindles on which the bobbins" aremounted, 11 the spindle-rail, 12 the lower or guide-rail, 13 thelifting-rod for the ringrail, let the shoe or foot at the lower end ofthe said rod, 16 the cross-shaft arm carrying the stud or pin 15, thelatter either acting diat 18 the crossshaft on which the said arm issecured, the said cross-shaft turning in bearings in brackets 19 (onlyone of which brackets is shown) and being caused to rock by usual meansfor the purpose of moving the ring-rail up and down.

All of the foregoing parts may be of any usual or preferredconstruction.

At 20 the separators are shown, and at 21 the rail on which theseparators are mounted.

At 22 is shown one of the separator-rods by the upper ends of which theseparator-rail 21 is supported, the said rod being held in up rightposition by a guide or guides 23.

In making provision for actuating the rod.

22 from the cross-shaft arm 16 simultaneously.

with theactuation of the ring-rail from the said arm, and in the samedirection but through a traverse of less extent, and also positively inboth directions, I contemplate employing various connections, differingamong themselves in minor structural details, but all embodying thesamegeneraland i characteristic elements or features and prin-;

ciples. The first of the essential elements or} features is the collar24, the said collar beingl slipped upon or applied to the separator-rod.Thesecond of the said essential elements or features is an appropriatesecuring or ad-} justing device by means of which the collarj 2-tissecured in place at an intermediate point in the length of theseparator-rod.

In the drawings I have shown the collarv held in place by means of aclamping-screw 25, which is fitted to a threaded hole in the collar andtakes bearing at its inner end; against theshaft. The third of theseessen-l tialelements or features is a connecting-rod, one instance ofwhich is the connecting-rod? 27 in Figs. 1, 2, 3, 4and 5, interposedbetween} the collar 24 and the cross-shaft arm 16, thel upper end, ofthe said connecting-rod being; pivotally or otherwise suitably connectedor} engaged positively with the collar, and the} lower end of theconnecting-rod being con-, nected likewise in a positive manner withthe} cross-shaft arm 16 as bya stud or pin 30 onf the said arm at apoint intermediate the axis-j on which the said arm turns and the pointat which movement is communicated to thelitt. ing-rod for the purpose ofactuatingthe ring-j rail. 1

The general considerations which lead to the employment of the foregoingfeatures the following: The said connectionsare such asto cause theseparator-rail and separators to rise and fall simultaneously with thering: rail and rings, but through a traverse of less: extent, as isnecessary in order that the separators may be maintained at all ti mesin proper position relative to the parts adjacent to which they are inthe spinning-frame, the connect-, ing-rod swinging laterally in allarrangements in which it is connected pivotally with the; collar, toenable its lower end to follow the; curve of the arc in which the studor pin 30 travels as the cross-shaft arm rises and falls.

By varying the point at which the collar 2t is fixed by the screw 25 tothe separator-rod 22, the height of the separator-rail and separators inthe spinning-frame may be varied as required, and, also, the traverse ofthe separators may be shifted or translated vertically without theextent of such traverse being changed.

It is found in practice, that cotton flyings continually collect uponthe surface of the separatorrod, particularly when such surface is roughor oily. It results, when the bearings through which the separator-rodslides vertically have been too loosely fitted to the said rod in thefirst instance, and also when the said bearings have become too largethrough the wear incident to use, that the cotton fiyings which collectupon the surface of the rod pass in betweenv the rod and the saidbearings, thereby clogging theopening between them, and this clogging,if not, relieved by the attendant, goes on increasing until theresistance due to it becomes so great as to overcome the tendency of theparts to fall of their own .weight after having been raised.l-Ieretofore, it has been customary to nearly counterbalance the weightof these partsand to depend upon the unbalanced portion of such weightto carry them down after being lifted, and it has resulted in practicethat the parts would not descend as intended ,when the bearings becameclogged, but would'remain for some time suspended, and then, perhaps asthe result of a jar, go down suddenly with a jerk. If, at such times,through the too great flexibility of the separator-rail, some of theseparators should strike against the ring-rail the regularity of, thewinding-on of the yarn would be disturbed. Asa complete safeguardagainst the obj ectionableresults of such clogging, I make the movementsof the separator-rod positive in both directions, as above mentioned, sothat if, in consequence of clogging, the separator-rod should sticksufficiently to prevent the separators from descending because of theweight of the parts, the machinery will draw them down.

It has been proposed heretofore to make the movements of the separatorspositive in both directions in separator-mechanisms of the samestructural type as that which isrepresented in the accompanyingdrawings, ,butin all known instances of this kind the constructionadopted has been of such character as to prevent adjustment such as isrequired in order independently to shift or translate vertically thetraverse of the separators. My present invention has as a special object,to entwisting or rotation.

28, of the connecting-rod is forked or split,

the arms 2929, of the fork, receiving between them the collar 24, andthe said arms being made to occupy positions at the front and rear sidesrespectively of the collar.

Screws 31, 31, are passed through the said arms and into the collar, toconnect the con meeting-rod and collar, and also to serve as pivots onwhich the connecting-rod can turn as it swings with the cross-shaftarm.' The connecting-rod is symmetrical on each side of the axial lineindicated in Fig. 3, and is of open construction, with the two sides3232, thereof, bowed apart and separated to the extent which isnecessary in order to provide against contact of the said sides with theparts which are located between them. The lower endof the connecting-rodis formed with a hole, 33, therethrough to receive the stud or pin, 30,projecting from the cross-shaft arm, 16, the said end being held-inplace upon the said stud or pin, 30, by means of a split pin, 34, passedthrough a hole in the free end of stud 30 outside of the connecting-rod.The lower end of the separator-rod extends down between thetwo arms,2929, of the forked upper end of the connecting-rod, and also betweenthe two sides 3232 of the said connecting-rod, while the said sides arelocated at opposite sides of the lower guide, 23, for the separator-rod.The construction is such as to enable the lower end of the connectingrodto be pivoted to the cross-shaft arm at a point on the latter which isso located that the horizontal component of the movement of the pivotalstud or pin 30, as it swings in a circular arc, shall be bisected by thecenter, line of the separator-rod. I consider this the best arrangement.It results in maintaining, at all times, in the movement of thecross-shaft arm, the point at which force is transmitted from thecross-shaft arm to the separator-rod as nearly as possible in line withthe separator-rod, and reduces to a minimum the side pressure andfrictionof the separator-rod in itsguide's. Also, the line of the forcetransmitted to the separator-rod from the cross-shaft arm is located inthe same vertical plane as the center line of the separator-rod, fromwhich it results that there is no tendency to twist or rotate theseparatorrod in its guides, and it is madeunnecessary to employ specialdevices to prevent such Further, in the case of the connecting-rod shownin Figs. 1 to 5 the force transmitted by means of the connectingrod istransmitted in a line passing through the axis of symmetry of theconnecting-rod. This form of connecting-rod may be made very lightbecause of the rigidity and strength secured by its structure.

A modified form of connecting-rod capable of securing similar results,but requiring to be made of somewhat heavier build in order to give itthe necessary rigidity and strength is represented in Figs. 6 and 7. Thedifference' existing between this form and that which has been describedis simply that in this form the connecting-rod is not made bilateral andsymmetrical, when viewed in the position represented in Fig. 7, but isunilateral and unsymmetrical. Both forms are sym metrical when viewedinthe position represented in Figs. 2 and 6. That part of the form ofconnecting-rod shown in Fig. '7, which is intermediate the ends thereof,is bowed sufficiently to provide against contact with the lower end ofthe separator-rod and the lower guide, 23. I

In the modification that is represented in Figs. 8, 9 and 10, thecollar, 24, is provided with a rearwardly projecting pin, 35, on towhich is fitted the upper end of the connecting-rod here designated bythe numeral 271, the said end of the connecting-rod having a holethrough which the pin, 35, passes, and theconnecting-rod being held inplace upon the pin, 35, by a split pin, 36, which is passed throughahole in the end of the latter. The connecting-rod at its lower end isformed with a hole therethrough to receive the stud or pin 30'projectingfrom the cross-shaft arm, 16, the said lower end being held in placeupon the said stud or pin by means of a split pin, 34, passing through ahole in the free end of the stud or pin outside of the connectingrod. Inthese figures I have shown the stud or pin formed separately from thecross-shaft arm and with a screw-threaded portion which is passedthrough a hole, 38, made transversely in the cross-shaft arm, 16. Thesaid hole may be either plain, or screw-threaded as shown. On the studor pin are placed nuts, 39, 39, fitting against the opposite sides ofthe cross shaft arm and serving to hold the stud or pin fixedlyin place.In this modification, in consequence of the'conneotion of the upper endof tion with the features already described as pertaining to thismodification a directing guide which shall hold the separator-rodagainst being turned or rotated on its axis,

'while, at the same time, it shall leave the said separator-rod free tobe moved up and down as required. A simple form of directingguide isthat shown in Figs. 8, 9 and 10.- In these figures, the projecting-heador end of the screw, 25, by which the collar, 24, is clamped in placeupon the separatorrod, passes into a vertical slot, 40, which isprovided in the upright portion or web, 41, of the stand 410 carryingthe guides 23-23, for the separator-rod. g

In all of the foregoing modifications, I have embodied a connecting-rodwhich ispivotally joined at its upper end toa collar on theseparater-rod, and is similarly joined at its lower end to thecross-shaft arm. This mode of construction and connection provides foractu-, ating the separator-rods with a minimum of resistance due tofriction resulting from the movements of the connecting devicesrelatively to and upon one another. In Figs. 11 and 12, I have shown afurther modification bearing in certain particulars of form a slightresemblance to that which is presented in Figs. 8' and 9, but resemblingthose which are presented in Figs. 1 to 7 in, having the line of theforce transmitted tof the separator-rod lying in the same vertical;

plane with the center line of the separatormeeting-rod, instead ofhaving the lower end of the said connecting-rod pivoted to the said-j InFigs. 11 and 12, the connect-; ing-rod is designated 272, and the slotin the stud or pin.

said connecting-rod in which plays the stud} or pin on the cross-shaftarm 16 is marked 42. The upper end of the connecting-rod is joined tothe collar at a point which is offset from the separator-rod, as in thecase of the con-i struction represented in Figs. 8 and 9. Inasmuch as inthis modification it is unnecessary for the connecting-rod to swing orvibrate lat-. erally as the cross-shaft arm moves up and down, theconnecting-rod and collar may be. formed integrally, as shown, orotherwise? fixedly connected togetherso as to form either actually orpractically one piece.

n the lower rail 12.

To hold the connecting-rod from vibrating or moving laterally, I applythereto a guide, 43, which is fitted to the said rod at some point whereit will not interfere with the mov: ing parts. In Figs. 11 and 12, Ihave shown the said guide as receiving the prolonged lower end of therod below the slotted por-. tion, and as forming a part of a stand,which is held by bolts 45, 45, and the nuts 46, 46, to The said boltsand nuts may be, as shown, those which secure the stand 410 to the saidrail 12. In this (3011- struction, inasmuch as the force by which theseparator-rod is moved up and down is applied always in a line which isparallel with the axis of the separator-rod and. sometimes is identicaltherewith, there is no tendency to rotate the separator-rod in itsbearings, and hence the directing guide of Figs. 8, 9 and 10, isomitted.

More or less work, in the shape of fitting and adjusting, ordinarily hasto be performed in applying and adapting separator mechanisms toring-frames. To economize labor,

trouble, and expenditure of time in this direction, I have devised anadjustable stand for the separator-rod which is so constructed as toadmit of being changed and shifted in a manner to meet all of therequirements or:

dinarily encountered in practice, and .to enable a separator mechanismto be quickly applied in exactly the desired and proper position andrelations. In Figs. 5, 6, 7 and 13, I have shown the details of the saidadjustable stand. In the remaining figures of the drawings I have shownonly an ordinary and simple form of stand, in order to avoid confusionand to secure simplicity in the said other figurest In Figs. 5, 6, and7, (see more particularly Fig. 6) the stand is shown composed of themain portion, 41, which is provided with the guides 23-23 for theseparatorrod and with the two separate brackets 411, 412. Two of suchbrackets are provided, in order to secure steadiness, but one alone maybe employed. The said brackets 411, 412, are formed substantially Lshaped, and through a horizontal slot 418 in the vertical part of eachis passed the stem of a headed bolt, 413, which also passes through avertical slot, 416, in the main portion, 41, the said bolt receiving onits threaded end a washer, 415, and a nut, 414,- for securing thebracket andthe main portion together. Thehorizontal part of each bracket411 and 412 has formed therein a slot 417 extending lengthwise of thesaid horizontal part, that is, at a right angle to the direction of theslot 418, and through this slot is passed the stem of the headed bolt,45, the said bolt receiving on its threaded end the washer, 47, and thenut, 46, by which each bracket is secured to its supporting rail 11 or12. The slots 416, 417, and 418, permit of, the guides 23, 23, beinggiven a range of adjustment universallyin all directions to theextentofthe limits imposed by the lengths of the said slots.

I do not herein lay claim broadly toa link pivotally connected at itsone end to the separator-rod and at its other end tothe crossshaft arm,nor to actuating mechanism for a separatonrod embodying such a link andalso adjusting means whereby the position of the separator-rail andseparators may be shifted Vertically, for these are claimed in myapplication for Letters Patent for improvements in separator-mechanismsfor ring-spinning frames filed February 10, 1893, Serial.
